Question

Hydraulic conductivity (\(K\)) is affected directly by which factor?

• A. Soil texture and fluid viscosity
• B. Catchment area
• C. Rainfall duration
• D. Basin slope

Hint:

Hydraulic conductivity depends on \[ \boxed{ \begin{aligned} &\text{Soil texture}\\ &\text{Void ratio}\\ &\text{Fluid viscosity}\\ &\text{Temperature} \end{aligned} } \]

Answer 1

The Correct Option is A

Hydraulic conductivity depends on the permeability of the soil and the properties of the flowing fluid. Soil texture controls the size and connectivity of pores, while fluid viscosity affects the ease of flow. Hence, \[ \boxed{\text{Soil texture and fluid viscosity}} \] is the correct answer. Therefore, \[ \boxed{(A)} \]
